玉米弯孢叶斑病菌毒素除草活性的研究
Study of Herbicidal Activity of Toxin Produced by Curvularia lunata
摘要
Abstract
The herbicidal activity of Curvularia lunata toxin was assayed and indicated by inhibition to seed germination and seeding growth of weeds.The results show that seed germination of Digitaria sanguinalis weeds were restrained by the toxin to 100％.But seed germination of Echinochloa crusgali and Setaria viridis weeds were restrained lightly.When the toxin was sprayed on seedling after growing for 3 d, the D.sanguinalis seedling growth was inhibited, but the toxin had no effect on seedling for growing for 7 d.The toxin did not affect the growth of E.crusgali and S.biridis seedling.The inhibition rate of Oryza sativa and Triticum aestivum were very low and the toxin was safe.关键词
